The Phoenix Contact CM 90-PS-230AC/2×12 DC/1 is a DIN rail-mounted power supply that converts 230 V AC input to dual 12 V DC regulated outputs. Engineered for industrial control and automation systems, this unit delivers 1 A per output with less than 30 mVss residual ripple. The compact 90 mm wide module integrates screw-type connections for both input and output, accommodating conductors from 0.2 mm² to 2.5 mm² (24–14 AWG). An LED indicator displays operating voltage status at a glance.
